Description

本発明は、カラー及びカラーの取付方法に関する。   The present invention relates to a collar and a method for attaching the collar.

従来から、カラーを挿入した被取付部材の取付孔にボルトを挿通させて、被取付部材を筐体等に取り付ける技術が提供されている。例えば、特許文献１には、被取付部材の取付孔と、ボルトの軸部との間にカラー（スペーサ）を介在させる技術が開示されている。そして、ボルトが挿通されるカラーの貫通孔は、ボルトの挿入方向に拡開される。従って、カラーの径方向の厚みは、ボルトの挿入方向に薄くなるように形成される。よって、ボルトを締め付けると、カラーのボルト挿入方向の端部外周が座屈してかしめられ、カラーは被取付部材の取付孔に固定される。   2. Description of the Related Art Conventionally, there has been provided a technique for attaching a member to be attached to a housing or the like by inserting a bolt into an attachment hole of the member to be attached into which a collar is inserted. For example, Patent Document 1 discloses a technique in which a collar (spacer) is interposed between an attachment hole of a member to be attached and a shaft portion of a bolt. The through hole of the collar through which the bolt is inserted is expanded in the bolt insertion direction. Accordingly, the collar in the radial direction is formed so as to be thin in the bolt insertion direction. Therefore, when the bolt is tightened, the outer periphery of the end of the collar in the bolt insertion direction is buckled and crimped, and the collar is fixed to the mounting hole of the mounted member.

An annular first groove portion is provided at a position adjacent to the inside of the wing portion on the end face on the one end side.

本発明のカラーの取付方法は、上記のカラーの取付方法であって、前記カラーを被取付部材の取付孔に前記羽部側から挿入させ、加圧具により前記羽部を前記本体部側に負荷を加え、前記羽部を前記本体部の径方向外側へ傾倒させることで、前記被取付部材を前記羽部と前記フランジ部とにより挟持させる、ことを特徴とする。   The collar mounting method of the present invention is the above-described collar mounting method, wherein the collar is inserted into the mounting hole of the mounted member from the wing portion side, and the wing portion is moved to the main body portion side by a pressurizing tool. A load is applied, and the wing portion is tilted outward in the radial direction of the main body portion, whereby the attached member is sandwiched between the wing portion and the flange portion.

本発明によれば、被取付部材の他の部材への取り付け安定性を向上するカラー及びカラーの取付方法を提供することができる。   According to the present invention, it is possible to provide a collar and a method for attaching a collar that improve the stability of attachment of a member to be attached to another member.

以下、本発明を実施するための形態について述べる。まず、カラー１の構成について図１〜図３を用いて説明する。なお、以下の説明では、カラー１の羽部１１が設けられる側を上とし、フランジ部１２が設けられる側を下とする。   Hereinafter, modes for carrying out the present invention will be described. First, the configuration of the collar 1 will be described with reference to FIGS. In the following description, the side on which the wing part 11 of the collar 1 is provided is the upper side, and the side on which the flange part 12 is provided is the lower side.

本実施形態のカラー１は、金属材料により形成することができ、全体が軸Ａｚを中心とする軸対称となるように略円筒状に形成される。カラー１は、本体部１０、羽部１１及びフランジ部１２を有する。本体部１０は円筒状に形成され、外周面１０２の下側にフランジ部１２が形成される。フランジ部１２と本体部１０の下面は、同一平面とされる。フランジ部１２の上側の外縁１２ａと、下側の外縁１２ｂは、各々Ｃ面取りされている。円筒状の本体部１０の中央は、上下方向に貫通する横断面円形の貫通孔１０１とされる。貫通孔１０１の上端側の内縁１０１ａと、下端側の内縁１０１ｂは、各々Ｃ面取りされている。   The collar 1 of the present embodiment can be formed of a metal material, and is formed in a substantially cylindrical shape so that the whole is axially symmetric about the axis Az. The collar 1 has a main body part 10, a wing part 11, and a flange part 12. The main body portion 10 is formed in a cylindrical shape, and a flange portion 12 is formed below the outer peripheral surface 102. The lower surfaces of the flange portion 12 and the main body portion 10 are flush. The upper outer edge 12a and the lower outer edge 12b of the flange portion 12 are each chamfered. The center of the cylindrical main body 10 is a through hole 101 having a circular cross section that penetrates in the vertical direction. The inner edge 101a on the upper end side and the inner edge 101b on the lower end side of the through-hole 101 are each chamfered.

本体部１０の外周面１０２は、上方部分が漸次縮径するよう形成される。より詳細には、外周面１０２は、フランジ部１２側の大部分を占める大径部１０２ａと、大径部１０２ａの上端から連設して羽部１１側へ向かって漸次縮径するテーパー部１０２ｂと、テーパー部１０２ｂから連設する小径部１０２ｃ（図３（ｂ）も参照）と、を有する。   The outer peripheral surface 102 of the main body 10 is formed such that the upper portion gradually decreases in diameter. More specifically, the outer peripheral surface 102 includes a large-diameter portion 102a that occupies most of the flange portion 12 side, and a tapered portion 102b that is continuously provided from the upper end of the large-diameter portion 102a and gradually decreases in diameter toward the wing portion 11 side. And a small-diameter portion 102c (see also FIG. 3B) provided continuously from the tapered portion 102b.

羽部１１は、本体部１０の外周側において本体部１０の上方である一端側から環状に連続する薄肉リング状に突出して設けられる。より詳細には、図３（ｂ）に示すように、羽部１１の外周面１１２は、本体部１０の外周面１０２である小径部１０２ｃと同径に形成される。羽部１１の内周面１１３は、羽部１１の先端側から基端側に向かって徐々に厚肉となるように傾斜している。羽部１１の先端には、平面状の先端面１１４が形成される。図３（ａ）及び図３（ｂ）に示すように、本体部１０は、羽部１１が設けられる一端側の端面１０３外周における羽部１１と隣接する内側の位置に、軸Ａｚ周りに環状の第１溝部１０４を有する。第１溝部１０４は、縦断面視において上方に向かって拡開する略台形状に形成される。従って、第１溝部１０４の内側の内壁１０４ａと外側の内壁１０４ｂは、それぞれ底部１０４ｃから上方に向かって傾斜している。内壁１０４ｂの壁面は、内周面１１３と直線状に連続している。底部１０４ｃの中央部分は、略平坦に形成される。   The wing portion 11 is provided on the outer peripheral side of the main body portion 10 so as to protrude from one end side above the main body portion 10 into a thin ring shape that is annularly continuous. More specifically, as shown in FIG. 3B, the outer peripheral surface 112 of the wing part 11 is formed to have the same diameter as the small diameter part 102 c that is the outer peripheral surface 102 of the main body part 10. The inner peripheral surface 113 of the wing part 11 is inclined so as to gradually become thicker from the distal end side to the proximal end side of the wing part 11. A flat tip surface 114 is formed at the tip of the wing 11. As shown in FIG. 3A and FIG. 3B, the main body 10 has an annular shape around the axis Az at an inner position adjacent to the wing 11 on the outer periphery of the end surface 103 on one end where the wing 11 is provided. The first groove portion 104 is provided. The first groove portion 104 is formed in a substantially trapezoidal shape that expands upward in a longitudinal sectional view. Therefore, the inner wall 104a on the inner side and the inner wall 104b on the outer side of the first groove portion 104 are inclined upward from the bottom portion 104c, respectively. The wall surface of the inner wall 104b is continuous with the inner peripheral surface 113 in a straight line. The central part of the bottom part 104c is formed substantially flat.

羽部１１は、外周面１１２と小径部１０２ｃの接続部（換言すれば、外周面１１２の基端）に、軸Ａｚ周り環状の第２溝部１１１を有する。第２溝部１１１は、縦断面凹円弧状に形成される。また、第２溝部１１１は、端面１０３よりも下方側（フランジ部１２側）に位置する。第２溝部１１１は、第１溝部１０４の底部１０４ｃと、上下方向に略同じ高さ位置となるように形成される。第１溝部１０４と第２溝部１１１の間に形成される羽部１１の基端部１１５は、下方における外周面１１２と内周面１１３との間よりも薄肉に形成される。そして、基端部１１５の肉厚中央部は、羽部１１の先端よりも、カラー１の径方向内側に配置される。従って、後述のカラー１の取り付け作業において、端面１０３より下方の基端部１１５を軸に、羽部１１を外側に傾倒しやすくすることができる。   The wing portion 11 has a second groove portion 111 having an annular shape around the axis Az at a connection portion between the outer peripheral surface 112 and the small diameter portion 102c (in other words, a base end of the outer peripheral surface 112). The 2nd groove part 111 is formed in a longitudinal cross-section concave arc shape. In addition, the second groove portion 111 is located on the lower side (flange portion 12 side) than the end surface 103. The second groove 111 is formed so as to be at substantially the same height as the bottom 104c of the first groove 104 in the vertical direction. The base end portion 115 of the wing portion 11 formed between the first groove portion 104 and the second groove portion 111 is formed thinner than between the outer peripheral surface 112 and the inner peripheral surface 113 in the lower part. The central thickness portion of the base end portion 115 is disposed on the radially inner side of the collar 1 with respect to the tip end of the wing portion 11. Therefore, in the mounting operation of the collar 1 to be described later, the wing part 11 can be easily tilted outward with the base end part 115 below the end face 103 as an axis.

つぎに、カラー１の取付方法について説明する。図４（ａ）はカラー１の取り付け工程において被取付部材２にカラー１を挿入した様子を示す図である。被取付部材２は樹脂等の可撓性を有するカラー１よりも柔軟な材料で形成することができる。被取付部材２は取付孔２１を有する。取付孔２１とカラー１の本体部１０（大径部１０２ａ）の径は略同径とされる。具体的には、取付孔２１の径は、本体部１０（大径部１０２ａ）が圧入されるように設定してもよいし、僅かなクリアランスで挿入されるように設定してもよい。また、カラー１の被取付部材２への取り付けは、ポンチ等の加圧具３により行う。加圧具３は、全体を図示しないが、例えば、端部に後述する凸湾曲面３１と平坦面３２を備えて棒状に形成することができる。   Next, a method for attaching the collar 1 will be described. FIG. 4A is a diagram illustrating a state in which the collar 1 is inserted into the attached member 2 in the attaching process of the collar 1. The mounted member 2 can be formed of a material softer than the flexible collar 1 such as a resin. The mounted member 2 has a mounting hole 21. The diameters of the mounting hole 21 and the main body portion 10 (large diameter portion 102a) of the collar 1 are substantially the same. Specifically, the diameter of the mounting hole 21 may be set so that the main body portion 10 (large diameter portion 102a) is press-fitted, or may be set so as to be inserted with a slight clearance. The collar 1 is attached to the member 2 by a pressurizing tool 3 such as a punch. Although the whole pressurization tool 3 is not illustrated, for example, it can be formed in a rod shape with a convex curved surface 31 and a flat surface 32 described later at the end.

カラー１の被取付部材２の取付孔２１の取り付けは、まず、カラー１の羽部１１側からカラー１を取付孔２１に挿入する。このとき、カラー１は、取付孔２１の内周面が羽部１１の外周面１１２に倣って、圧入の場合はテーパー部１０２ｂにより広げられるようにして、挿入される。従って、カラー１は取付孔２１にスムーズに挿入することができる。羽部１１側から挿入されたカラー１は、フランジ部１２の上面１２２が被取付部材２の下面２２と当接するまで挿入される。第２溝部１１１は、上面２３よりも外側に位置するよう設定される。   To attach the attachment hole 21 of the attached member 2 of the collar 1, first, the collar 1 is inserted into the attachment hole 21 from the wing part 11 side of the collar 1. At this time, the collar 1 is inserted so that the inner peripheral surface of the mounting hole 21 follows the outer peripheral surface 112 of the wing portion 11 and is expanded by the tapered portion 102b in the case of press-fitting. Therefore, the collar 1 can be smoothly inserted into the mounting hole 21. The collar 1 inserted from the wing portion 11 side is inserted until the upper surface 122 of the flange portion 12 contacts the lower surface 22 of the attached member 2. The second groove 111 is set so as to be located outside the upper surface 23.

図４（ｂ）は、加圧具３の凸湾曲面３１により羽部１１を傾倒させる様子を示す図である。カラー１を取付孔２１に挿入した後、端面１２１を被取付部材２とともに平坦な作業台等に載置させる。そして、上方から羽部１１より大径の加圧具３の凸湾曲面３１を羽部１１の先端に当接させて、ハンマー等により加圧具３の後端を打ち付け等して、羽部１１に対しカラー１側に向けて負荷を加える。すると、羽部１１の先端が、凸湾曲面３１の接点から径方向外側への分力を受けて、羽部１１は、第１溝部１０４及び第２溝部１１１により薄肉となった基端部１１５を軸として、カラー１の径方向外側へ傾倒する。羽部１１は、図４（ｂ）に示すように、凸湾曲面３１の一部がカラー１の内縁１０１ａに当接するため、所定の傾倒角度で止まる。   FIG. 4B is a diagram illustrating a state in which the wing part 11 is tilted by the convex curved surface 31 of the pressurizing tool 3. After the collar 1 is inserted into the mounting hole 21, the end surface 121 is placed together with the mounted member 2 on a flat work table or the like. Then, the convex curved surface 31 of the pressurizing tool 3 having a diameter larger than that of the wing part 11 is brought into contact with the tip of the wing part 11 from above, and the rear end of the pressurizing tool 3 is struck with a hammer or the like. A load is applied to 11 toward the color 1 side. Then, the tip end of the wing part 11 receives a component force radially outward from the contact point of the convex curved surface 31, and the wing part 11 has a base end part 115 thinned by the first groove part 104 and the second groove part 111. Is tilted outward in the radial direction of the collar 1. As shown in FIG. 4B, the wing portion 11 stops at a predetermined tilt angle because a part of the convex curved surface 31 comes into contact with the inner edge 101 a of the collar 1.

図５（ａ）は、加圧具３の平坦面３２により羽部１１を傾倒させる様子を示す図である。図４（ｂ）の傾倒させた羽部１１に上方から加圧具３の平坦面３２を当接させ、ハンマー等により加圧具３を打ち付け等して、羽部１１に対しカラー１側に向けて負荷を加える。すると、羽部１１は、カラー１の径方向外側へさらに傾倒する。このとき、羽部１１は、平坦面３２がカラー１の端面１０３に当接することで、羽部１１の内周面１１３の先端とカラー１の端面１０３とが略同一平面となる位置まで傾倒することができる。   FIG. 5A is a diagram illustrating a state in which the wing part 11 is tilted by the flat surface 32 of the pressurizing tool 3. The flat surface 32 of the pressurizing tool 3 is brought into contact with the tilted wing part 11 of FIG. 4B from above, and the pressurizing tool 3 is struck with a hammer or the like to bring the wing part 11 to the collar 1 side. Add a load toward. Then, the wing part 11 further tilts outward in the radial direction of the collar 1. At this time, the wing portion 11 is tilted to a position where the tip of the inner peripheral surface 113 of the wing portion 11 and the end surface 103 of the collar 1 are substantially flush with the flat surface 32 coming into contact with the end surface 103 of the collar 1. be able to.

図５（ｂ）は、被取付部材２へのカラー１の取り付け工程が終了した様子を示す図である。被取付部材２は、フランジ部１２と、傾倒後の羽部１１とにより挟持される。   FIG. 5B is a diagram illustrating a state where the attaching process of the collar 1 to the attached member 2 is completed. The mounted member 2 is sandwiched between the flange portion 12 and the wing portion 11 after tilting.

このように、羽部１１を傾倒させることで、カラー１は、取付孔２１の縁部周辺を、羽部１１とフランジ部１２とにより挟持して、被取付部材２に対し脱落しないように取り付けることができる。また、カラー１は、専用工具を使用することなく凸湾曲面３１や平坦面３２を有した簡易な工具でかしめることができるため、容易に取付孔２１の補強材として用いることができる。   In this way, by tilting the wing part 11, the collar 1 is attached so that the periphery of the edge of the attachment hole 21 is sandwiched between the wing part 11 and the flange part 12 so as not to drop off the attached member 2. be able to. Moreover, since the collar 1 can be caulked with a simple tool having the convex curved surface 31 and the flat surface 32 without using a dedicated tool, it can be easily used as a reinforcing material for the mounting hole 21.

以上、本実施形態では、筒状の本体部１０が、一端側に延設される羽部１１を有し、他端側にフランジ部１２を有し、更に、一端側の端面外周における羽部１１の内側に隣接する位置に環状の第１溝部１０４を有するカラー１について示した。したがって、カラー１は羽部１１を被取付部材２へ傾倒させて一端側に平坦な面を容易に形成することができ、カラー１と、カラー１に接する他の部材との接触面積を増加させて、被取付部材２の取り付けを確実に行うことができる。また、カラー１は、羽部１１を径方向外側に安定した基端部１１５の位置で容易に傾倒させることができ、かしめ状態を確実にして被取付部材２からの脱落が防止される。そのため、被取付部材２の他の部材へ取り付け安定性を向上させることができる。   As described above, in the present embodiment, the tubular main body portion 10 has the wing portion 11 extended to one end side, the flange portion 12 on the other end side, and the wing portion on the outer periphery of the end surface on the one end side. 11 shows the collar 1 having the annular first groove portion 104 at a position adjacent to the inner side. Therefore, the collar 1 can easily form a flat surface on one end side by inclining the wing part 11 toward the attached member 2, thereby increasing the contact area between the collar 1 and other members in contact with the collar 1. Thus, the attached member 2 can be reliably attached. Further, the collar 1 can easily tilt the wing part 11 at the position of the base end part 115 which is stable radially outward, and the caulking state is ensured to prevent the detachment from the attached member 2. Therefore, it is possible to improve the attachment stability to other members of the attached member 2.

なお、加圧具３をカラー１の径方向外側へ傾倒させる等しながら、羽部１１を全周に亘りフランジ部１２側へ負荷を加えることで、羽部１１の先端が端面１０３よりもフランジ部１２側に位置するように、羽部１１をさらに傾倒させることもできる。これにより、羽部１１とフランジ部１２で被取付部材２をさらに狭圧して、カラー１の両端に、平坦な面（端面１２１と端面１０３）を形成するとともに、カラーの軸方向への移動を防げることができる。   The tip of the wing part 11 is more flanged than the end face 103 by applying a load to the flange part 12 side over the entire circumference while tilting the pressurizing tool 3 radially outward of the collar 1. The wing part 11 can be further tilted so as to be positioned on the part 12 side. As a result, the attached member 2 is further narrowed by the wing part 11 and the flange part 12 to form flat surfaces (the end face 121 and the end face 103) at both ends of the collar 1, and the collar can be moved in the axial direction. It can be prevented.

また、本実施形態のカラー１は、軸Ａｚに軸対称な形状で構成されるため、旋盤加工等により安価で容易に製造することができる。   Further, since the collar 1 of the present embodiment is configured in an axisymmetric shape with respect to the axis Az, it can be easily manufactured at a low cost by lathe processing or the like.

また、被取付部材２にかしめたカラー１は、一端側の端部を平坦な端面１０３とし、他端側の端部も平坦な端面１２１としている。そのため、カラー１に対してボルトやナット等の締結具を面当接させることができ、締結具の緩みを防止することができる。したがって、被取付部材２を他の部材に確実に固定することができる。   In addition, the collar 1 crimped to the attached member 2 has a flat end face 103 at one end and a flat end face 121 at the other end. Therefore, a fastener such as a bolt or a nut can be brought into surface contact with the collar 1 and loosening of the fastener can be prevented. Therefore, the attached member 2 can be reliably fixed to another member.

なお、本実施形態では、円筒状に形成されたカラー１について示したが、カラー１全体を矩形筒状としてもよい。また、羽部１１は、本体部１０の周方向に対し間欠的な切欠を備えるリング状に設けてもよい。この場合、第１溝部１０４及び第２溝部１１１は、羽部１１が形成される位置に対応させて、間欠的な環状に設けることができる。さらに、羽部１１は、本体部１０の一端側においてリング状とならないように（例えば羽部１１を２箇所に設ける等により）設けてもよい。   In the present embodiment, the collar 1 formed in a cylindrical shape is shown, but the entire collar 1 may be formed in a rectangular cylindrical shape. Further, the wing part 11 may be provided in a ring shape having intermittent notches in the circumferential direction of the main body part 10.
